What's a good way to keep flywheel still?

[allbaugh_04]

I used a couple of screwdrivers wedged into the flywheel.....just takes some engineering to get them in there right and tight enough but they'll hold. I have an impact but the problem is my impact only goes to like 150 ft/lbs I think and wasn't strong enough to break the bolt loose. Are you putting a stock bolt back in or ARP? I went with ARP and it gets some ungodly amount of torque applied to it to get the bolt back on there.....like 240 ft/lbs I think. I did get the wrench to click but I couldn't tell if it was the wrench clicking or one of my vertebrae.

I bought a gasket kit from Texas Speed, it's supposed to include a new bolt i think.
